Serving as a prequel to its predecessor, Bob Odenkirk will reprise his role as shady attorney Saul Goodman, before he began representing chemistry teacher-turned-meth kingpin Walter White (Bryan Cranston) and his associate Jesse Pinkman (Aaron Paul).

On "Breaking Bad," Ehrmentrout would help out with Goodman's dubious affairs from time to time, but he primarily served as the right hand man for meth lord and Pollos Hermanos franchise owner Gus Fring (Giancarlo Esposito), before then going on to work for White, a.k.a. Heisenberg.

So far, Odenkirk and Banks are the only "Breaking Bad" cast members officially confirmed to appear in the spinoff, but Cranston and Paul have both publicly expressed interest in reprising their roles.
